CAMERA.

Application filed June 7, 1915.

To all whom z'zf may concern.'

Re it known that I, VILLIAM A. PETERS, a citizen of the United States,residin at Chicago, in the county of Cook and tate of Illinois, haveinvented certain new and useful Improvements in Cameras; and I do herebydeclare the following to be a' full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to improvements in photographic cameras and moreparticularly to bellows cameras of a certain type r types in whichspace. is required` for the movement of a certain part or parts Withinthe casing which necessitates the provision of additional space forhousing the bellows and lens-board carriage when the camera is folded.

The main object of thc present invention is to provide means in a cameraof the-type or types referred to for housing all of the internal partsrequiring operating space within so much space as is ordinarily requiredby one of said parts.

My invention relates essentially to the particular type of cameraillustrated and described in my copending application for patent, Ser.No. 859612, iled Sept. 1, 1914, but may be successfully adapted to othertypes having internal operative parts requiring space. I referparticularly to carneras of the type illustrated and described-inLetters Patent to J. D. Gareld No. 713,629 dated Nov. 18, 1902, and- No.932,457, to W. F. Folmer. dated Nov. 18, 1902, and all others in whichsubstantially the same conditions prevail.

The invention consists in the features of construction and combinationsof parts hereinafter fully described and claimed.

In the accompanying drawings illustrating that embodiment of myinvention adapting it for use in the camera illustrated and described inmy aforesaid copending application: f

Figure 1 is a vertical section through a closed camera constructed inaccordance with my invention.

Fig. .2 is a fragmentary vertical section through the same camera withthe bellows member in its operative position.

Fig. 4.- is a fragmentary vertical section looking forwardly of thecamera and showing the means for guiding the rear end of the bellowsmember.

Fig. is an enlarged upward view of the cam element of Fig. 3.

Fig. 6 is a fragmentary horizontal section showing the means for lockingthe rear bellows frame against movement relatively to the auxiliarytrack section.

Fig. 7 is a vertical section along the line 7-7.

Fig. 8 is an enlarged upward view of the under side of the lens front.

In the embodiment illustrated, the casing 1 of the camera houses a pairof spool holders 2 and 3, which may be moved within the casing so as tostretch successive portions of through Fig. 6

- the ilm vl within the `cone of light of the camera. When the camera isnot in use, these'spool holders are moved by the actuating rod into thebottom of the casing, where they are stored substantially outside thecone of light of the camera, as shown in Fig. 1. The casing 1 isequipped with a pivotal drop front 6, which may be disposed as in Fig.2, thereby affording an anterior opening through which the bellowsmember ofthe cameray may be projected. This bellows `member consistsessentially of a. lens board carriage 7 connected to a rear bellowsframe 8 by bellows 9, the total length of the bellows member andlens-housing when compacted being less than the interior depth of thecasing. The frame 8 has integral with its lower portion a. forwardlydirected projection 10 adapted to overhang the hinges of the drop front6 when the bellows member is extended, thereby prevent-- ing a leakageof light into the casing through the joints of these hinges. rlhe otherthree sides of the frame 8 have forwardly directed flanges 11 whichflanges overhang rearwardly directed :flanges 12 on the front of thecasing when the bellows member is in the position of Figs. 2 and 3. Theframe 8 also has at its opposite sides angle-sectioned guides 13slidably fitting into guideways 14 carried by the casing, whereby thesaid frame together with the bellows (and lens board carriage carried bythe same) may be guided back and forth with respect. to the casing.

The front table 6 has the usual track 15 for the lens board carriage,the latter being sure for said opening, a bellows, a frame connectedwith one end thereof movable within said housing, and adapted to engageportions of said wall bordering said opening for limiting the movementof said frame in one direction, a lens-board connected with the otherend of said bellows, a carriage for the same adapted to travel on saiddropfront toward and from said wall of the housing, andtension-imparting means asso* ciated with said bellows frame and saiddrop-front for firmly holding said frame in engagement with said wall ofsaid housing when said bellows is expanded.
